Очень классное расширение

schon

Funciona como esperado e dá para escolher entre qualquer tema já instalado no FF para ambos os modos. Ótimo!

Nice idea, but the option to change theme based on system doesn't work for me. To be more accurate, it works inconsistently: sometimes it changes it, sometimes it doesn't.

Absolutely wonderful addon! I had no idea this was possible. Firefox is horrible at day/night switching and this addon does it PERFECTLY. Thank you so much.

This extension has become an integral part of my browser

It would be nice if it could use input latitude and longitude, I used proxy software that caused the positioning to be random

thanks for your support

Doesn't work. Many issues open on the github page about this. This isn't maintained.
